According to the latest plan put forward by the ministry of railways, 26,000 km of new lines will be put into operation between 2010 and 2012, including 9,200 km of dedicated passenger lines. At present, the amount of nylon engineering plastics used in railway planning and construction in China exceeds 7 tons per kilometer, and 5,000 sets of fasteners are used per kilometer. The rapid development of high-speed railway has driven the rapid growth of nylon demand in China.

It is reported that foreign advanced countries in the 1970s began to modify the nylon engineering plastics used in railway fasteners. After more than 30 years of use and verification, modified nylon engineering plastics have been widely used in track gauge blocks, baffle blocks and sleeve fasteners. Nylon used in high-speed railway, can effectively solve the problem of locomotive shaking, noise, and can ensure the stability of wheelbase, reduce the number of maintenance, especially it has excellent vibration resistance, to ensure the smooth operation of high-speed railway locomotive is very important. Compared with metal parts, nylon parts have light weight, rust resistance, shock resistance, long-term thermal stability and good insulation, and high liquidity, excellent processing performance, design flexibility, easy to achieve integration of parts, reduce the number of parts and assembly process, improve the installation efficiency, easy to maintain.
